. As the looper is withdrawn or recedes, the yarn is carried with it,and the loop is formed in connection with the cylinder needles, the yarnbeing alternately engaged with the looper hooks and cylinder needle andheld until same has passed the body wales or web- .forming point.Opposed to the brush 24, and

carried removably upon the periphery of the disk 11, is the looperretainer 25, the urpose of which is to prevent any upwa r movement ofthe loopers as they are projected to engage the yarn and return with thesame.

A t 'ter the 'web' has been formed, and to properly feed the same withinthe cylinder and not injure or-break the web, as is customary with-thestress devices now used, I

i v employ the'rotary depressor or'feedcr 26, which is journaledupon'the angular frame 27, carried upon the periphery of the disk 11;the wheel being disposed at such an angle as to have its peripheral edgeenter the spacebetween the dis: and cylinder far.

enough to press the finished web below the needles. The web-pressingwheel or disk 26 is pivotedin oblique fixed bearings at the extremerecession point of the.cylinder-and dial needles, and therefore retainsthis relative position at all times.

:In Figs. 5 and 6, the loopers 28, are mounted in the same verticalline, as the needles 29, the loopers being below andof course havingtheir shanks 250, in the same radial line, but nearer the center thanthe shanks 31 of the needles;

From the foregoing description, taken in connection with the drawings,the operation of my machine is readily understood, but briefly stated,it is as follows 1tefcrring to Fig. 1'- and to the left hand sidethereof, the cylinder needles have and retain theweb yarn a, and aregradually rising as at b to insure the latches falling, but not'hig'hfenough to cause the yarn a,- tdfa'll below the latches.Theloopers as the pass theyarn guide, hook the yarn c an as the cylinderneedles pass this point,

the catch the yarn 0, the loopers receding to,- orm the "loop while thecylinder needles a's'sist them' byoldin'g 'the yarn; As the dial tndcylinder revolve toward the right, the yarns (Land 0 are carried bytheneedles and the loopers, the cylinder needles as they approach theyarn d, at e, being projected higher than at b, the yarns a and a slidedown below the latches, so that after the cylinder presser wheel 26, theyarn 4, still remaining in the cylinder and dial needles.

In Fig.4, I have illustrated the operation ofthe needles and loopers,-with the looper yarn in diagram. From this it will be clearly seen thatthe loops 7, are formed and secured in the Web; the loopers for form ingthe loops, at all times, operating below and within the needles of boththecylinder and dial, and upon the receding; or pull stroke of theloopers. WVhat I claim, as new, is

the dial needles having moved 1. In a knitting machine, the combinationofa cylinder and a dial, needles carried. by the cylinder and dial,loopers'carried'by the dial, said dial, having radial grooves .to

receive a needle and a looper inone and the same groove so as to permitsaid needle and looper to slide longitudinally in the groove and meansfor operatin loopers independently 0 each other, said loopers operatingto engage the looping yarn from below and within the needles to formloops upon the pull stroke.

2. In a knitting machine, thecombination of a'cylinder, needles mountedtherein a cam to operate said needles, a dial provided with radialgrooves fitted to receive and permit a needle and looper to slid'elongitudi nally in each groove, a cam for operating the needles and acam for operating the .loopers, said loopers operating to engage thelooping yarn from below and. within the needles to form loops upon thepull stroke.
